Of the tribe of Simeon [were] sealed twelve thousand. (6) Of the tribe of (b) Levi [were] sealed twelve thousand. Of the tribe of Issachar [were] sealed twelve thousand.
(6) Here the tribe of Levi is listed with the rest, because all the Israelites were equally made priests with them in Christ by his priesthood (Romans 12:1; 1 Peter 2:9; Revelation 1:6; Revelation 5:10). Dan is not mentioned, because the Danites long before forsaking the worship of God, were fallen away from the fellowship of God's people, to the part of the Gentiles: which evil many ages before Jacob foresaw (Genesis 49:17-18), and because of which no mention is made of this tribe in the book of Chronicles.
(b) He skipped Dan, and reckons Levi.
